Confirmation dialog improvements
After Effects does not bother the user with distracting dialog boxes since the undo actually works as intended. Similarly Premiere Pro shouldn't pop up unnecessary dialog boxes such as the one confirming if the user is sure they want to clear the keyframes. After Effects gets away without such a dialog box an no-one ever asked to have one added. Similarly Premiere doesn't need such dialog boxes. Optionally, make them pop-up but provide check boxes such as "do not ask again" to allow the user to configure the behaviour as suits them best. (Then provide a means of resetting all hidden diaologs just in case a user wasn't to show them again.)
I'd like the option to disable ALL warning dialog boxes, not just for the keyframes.
